If you are using boiled beetroot, cut it in cubes. If you are using uncooked beetroots, shred it, as it will quickly soften while cooking.
In a pan add oil, once hot, add chana dal, and walnuts. Sauté the chana dal and walnuts until crispy and turn golden.
Now add the cubed or shredded beetroots. If you are using uncooked beetroot, sprinkel some water, to cook them until soft.
Now add freshly grated coconut or frozen shredded coconut.
Mix everything well. Turn off the flame. And let it cool down.
Once cool, add everything to a blender jar.
Blend it dry. Now add 2 tablespoons of water and pulse. Add more water if you need to.
Pulse the chutney as per your desired consitency. I like to grind this chutney think and not runny in consistency.
Once the chutney is ready, take it out in a serving plate.
In a small pan, add oil. Once hot add mustard seeds, urad dal and let them splutter.
The urad dal will quickly turn golden. Take it off the flame.
Now add slit green chilies and curry leaves.
Pour this tempering into the prepared chutney and mix well.
Serve it with dosas, idlis, paniyarams or even use it as a spread for sandwich!
